Application filed September {52, 1W6, No. l

The gencrel object of my present invention is to provide unimproved construction of it stopper ot the general type commonly used to ieinovnbly close lavatory rei epteclc drsuu outlets lliore specifically, the object of my invention is to provide on improiwd town of stopper insert tor detztchnbly connecting the stopper to the chain or analogous device ord1- nurily connected to the waste or drain outlet opening stopper oil. it lavatory receptor-lo or the like.

The various teuttu'es of novelty which chin" :icterisc my invention are minted out with psrticulztrity in the claims zinnc iedto and torniing it part oi? this specification. For it better uiulerstnmli11g oil the invention, however, its udventnges and specific objects at mined with its use, ref ico should be had to the eccoin mnying drawings and descriptive mutter in which have illustrated and described preferred cml'iodilnents of my incntion.

()2? the drawings:

Fig. l is o perspective view of e stopper end attached chitin;

Fig. 2 is a vertical sect-ion o'l 2L partially nuuiutdctured stopper; v

Fig. 3 is n vertical section of the stopper shown in 1;

ltlg. t is it plain view of the stopper; and

Fin. 5 is a perspective view ot the insert in :uTinterniediztte stage or form.

The stopper shown in the drawing co1nprises a plug or body A o'l moulded rubber shaped in the usual :torin linbedded in the body A is the enlarged base portion of on insort B hoving an externally projecting end portion in the -fol-n1 of a loop or staple, the tree end oft which is incontact Withtho upper surtuce oi the rubber body A or, preferably, is :t'orced slightly below the surface thereof.

In the preferred form oi. the invention as shown by the drawings the insert is in the term ot a metallic wire having one end bent into circular term and imbedded in the rubher body and having its other end extending radially inward towards the center of the base circlennd then turned in a vertical direction to form a vertical projecting end. The projecting end is bent into the form oi rt staple or loop-like portion to which a chain Ginny be attached.

in the ordinarynizmutztcture of my inven tion the insert B with its tree end portion unbent as shown in Fig. 5,, is placed in the mold in which the rubber body A is to be formed with the circular port of the insert in a liorizoutul plane in the lower hell of the mold and held in that position by any suitable moons. After the stopper body has been formed and has been removed from the mold, the ports then being; in the term as shown in Fig. 2, the vertical upper portion of the in sort B is bent into n loop preferably with the verticnl legs spaced opproxinintely cquidis tent from the center oi? the circuler top of the stopper as shown in 2-3. A chain C may then be attached to the stopper the free end of the external inse tion s1 .ently to permit the chain link to be inserted under the open end of the loop, which is then restored to its position in con- "L tCt with or below the top surface of the stopper.

The wire used in the construction described in ordinarily sutliciently still so tlutt the loop portion is not liable to become bent due to the stresses caused by the chain when the stopper is being removed tron: the drain outlet. The rigidity of the insert and the arrangement oi the tree end of the loop below the top surface oi the body it prevents the clniinlinla: from becoming disengaged with the loop while in use, but the tree end 01": the loop may be pried up to disconnect the chain \vhcnever this becomes necessary us to client stopper-body renewztls. This feature oi the invention is especially important as rubber stopper bodies frequently become worn utter constant use and must be replaced.

l Vhile in accordance with the provisions of tl'iestotutes, I have illustrnted and describedthe best term of einbodiu'ient of my invention now known to me, it will benpparent to those sltilled in the art thot changes may be made in the form of the apparatus disclosedwithout departing iron) the spirit ol' my invention its set forth in the appended claims and thetin some cases certain features of my invention may housed to advantage without a corresponding use of other teotures.

Having now described my invention, whet I desire to secure by letters Patent, is:

1. A plug stopper adapted to be removably seated in {t lavatory port, comprising at plug body and a separate pert inchulinp; a base portion nnbedded in said body and or portion projecting from the top surtzice off y p y ll loop porsaid body and so bent that its "free end is normally in engagement with said body, said body andfport having such limited relative elasticity that said free end is not Withdrawn from contact with said body by the force normally required to unseat said stopper but by the application of a greater force, said free end may be separated from said body to permit said free end to be inserted into or re moved from an apertnred attachment to said stopper-Q V v [2.- A'plngstopper adapted to be removably seated in a lavatory port eomprising an elas-
